SADDLE FOR TOP ROLLS OF SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 352,634, dated November 16, 1886.

Application filed March 3, 1886. Serial No. 193,905.

To all whom it may concern:

Be it known that I, AMos B. TAYLOR, a citizen of the United States, residing at VVollaston, in the county of Norfolk and State of Massachusetts, haveinvented certain Improvements in Saddles for Top Rolls of Spinning-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which Figure 1 is a plan of my improved saddle in working position upon the saddle-bearings of the top rolls of a spinning-machine. Fig. 2 is a longitudinal vertical section of the same, the saddle being represented as hearing on all three of the top rolls. Fig. 3 is a similar section representing the saddle bearing on the front and rear rolls only, and so adjusted by its regulating-screw as to be lifted out of contact with the middle roll, which is thereby relieved of the pressure of the saddle weight. Fig. 4 is a transverse vertical section of the saddle, taken in a plane passing through the regulating-screw. Fig. 5 is a transverse ver-' tical section on the line a; m of Fig. 2.

My invention relates to saddles for top rolls of spinning-machines, and has for its object to provide a simple means whereby the middle roll may be entirely relieved of the pressure of the weight which is applied to the saddle, or the said weight caused to exert more or less pressure on the middle roll, as may be desired, thus enabling the machine to be easily and quickly adjusted in case the roving should be found to contain cotton of longer staple than that ordinarily used for the purpose. This sometimes occurs from a few bales of longstaple cotton becoming accidentally orunintentionally mixed with the ordinary cotton in the picker-room of the mill; and much inconvenience and trouble are often experienced when a portion ofthe roving is suddenly found to contain this long-staple cotton, for the reason that some of the fibers will then exceed in length the distance between the middle and front pairs of rolls, and will in consequence be either broken or stretched, which will result in the production of cockled or kinked yarn unfit for use. Therefore, when a portion of the roving is suddenly found to contain this long-staple cotton, it becomes necessary to stop the spinning-machine and adjust the va- (No model.)

the top rolls of spinning-machines composed of an upper section provided with a slot or aperture, and a lower section connected together by a regulating-screw passing through the slot or aperture in the upper section into a threaded aperture in the lower section, and so arranged with relation to the fulcrum or bearing-point of the upper uponthe lower section of the saddle that as it is turned the inner end of the lower section will be raised,

to relieve the middle roll of the pressure of the saddle weight, or depressed to apply the pressure of said weight to the middle roll, by which construction the necessity of stopping the machine and varying the distance apart of the front and middle rolls by adjusting the boxes or bearings of the former is avoided, as the long fibers of the cotton, being no longer held by the middlepair of ro1ls,when thepressure of thesaddle weight is removed therefrom, can be drawn by the front rolls without liability of being broken or stretched, and no kinks or cockles will be produced in the yarn,while the simple vertical adjustment of the two sections of the saddle by means of the regulating-screw, which can be effected when the machine is in motion, will adapt it for roving of any description which may be passing through the rolls. In the said drawings, A B 0 represent the top rolls of a spinning-machine, and D the saddle, which is composed of an upper section or portion, 6, and a lower section or portion, f, these sections, when in the position represented in Fig. 2, resting onthe saddle-bearings of all three of the top rolls, A B O, which is their normal condition, the usual stirrup, g, being provided, which bears on the upper section, 6, of the saddle at h, and is connected with a weight, (not shown,) by means of which the required downward pressure is exerted upon the rolls.

The upper section, 6, of the saddle bears at its inner end at 2' upon the lower section,f, and the two sections, f, are connected together by a vertical screw, G, which passes loosely through 5 a slot or aperture, k, in the section e, and is turned into a correspondingly-threaded aperture, 10, in the section f, the screw G being located in front of the fulcrum or bearing i of the upper upon the lower section, and a space, I, be

I0 ingleftbetween the two to admit of the inner end of the lowersection being drawn up by the screw G, as seen in Fig. 3, to raise it out ofcontact with the middle roll, B,which is then relieved of the pressure of the weight applied to the saddle I 5 through the stirrup g. The inner end of the upper section, e, is provided at its bottom with a tongue orprojection, 'm.,which fits within a longitudinal groove, n, in thelower section, f, and serves as a guide to keep the two portions in line with each other when adjusted longitudinally to adapt them to the distance between the front and rear rolls, A 0, this adjustment being permitted by the slot 70 and screw G.

From the foregoing it will be seen that with a saddle constructed as above described, when roving of the ordinary character is being used the fibers of which are of less length than the distance between the rolls A B, the parts can be adjusted to cause the saddle to bear equally 0 upon all three of the top rolls, as seen in Fig. 2; but in case the roving should suddenly be .found to contain cotton of longer staple, the fibers of which are of greater length than the distance between thefast-moving roll A and the 3 5 middle roll, B, it is merely necessary to turn the screw G, while the machine is still in motion, until the inner end of the lower section, f, of the saddle is raised out of contact with the middle roll, B, as seen in Fig. 3, when 40 the pressure of the saddle weight will be entirely removed therefrom, leaving only the weight of the roll B upon the roving, and all liability of the fibers becoming broken or stretched, as would otherwise occur,is avoided,

5 and the production of kinked or coekled yarn thus effectually prevented, while as soon as roving of the ordinary description is again found to be running through the machine it is merely necessary to turn the screw G back again and lower the inner endof the lower section, f, into contact with the middle roll, B, these adjustments being easily and quickly effected without stopping the machine, where'- by a great saving in time and labor is eifected and vexatious and expensive delays avoided and it will be seen that my improved saddle is thus adapted for use either where it is desired to maintain a pressure upon all three of the top rolls or only upon the front and rear rolls. It will also be seen that the screw G serves to hold the two portions or sections of the saddle together, so that when lifted from the rolls they will not become separated, and consequently the liability of loss or misplacement is greatly diminished.

I do not claim, broadly, a saddle for top rolls composed of two members adjustable lengthwise relatively to each other, and provided with means for adjusting the saddle so that it may exert pressure upon all the rolls or only '70 upon the outermost ones of the series.

1. A saddle for the top rolls of spinningmachines, composed of an upper section provided with a slot or aperture, and a lower section connected therewith by a screw passing through the slot or aperture in the upper section into a threaded aperture in the lower section, and arranged with relation to the fulcrum or bearing-point of the upper upon the lower section of the saddle, as shown, whereby the inner end of the lower section is raised out of contact with or brought down upon the middle roll, substantially as and for the purpose set forth.

2. The combination of the lower section, f, the upper section, e, bearing thereon at z, and provided with a slot or aperture, is, and the regulating-screw G, passing through the slot or aperture 7c in the upper section, 6, into a threaded aperture in the lower section, f, whereby as the screw G is turned the inner end of the lower section, f, will be raised to relieve the middle roll of the pressure of the saddle weight, or depressed to apply the press- 9 5 ure of said weight to the roll, substantially in the manner and for the purpose described.

Witness my hand this 2d day of March, A. D. 1886.
